To all whom it may concern: I

Be it known that I, FRANK L. RosENTnETER, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Looks for Meeting- Strips for Window-Sashes; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form part of thisspecification, in which Figure 1 is a perspective view showing myimproved window-sash meeting-rail fastener applied to portions ofthemeeting rails of two sashes. Fig. 2 is a vertical transversesectionthrough the center of the device when locked.

Fig. 3 is asimilar view indicating the position.

of the parts when unlocked. Fig. 4 isa bottom view of the case, showingthe internal parallel guides for the locking-bolt. Fig. 5 is aperspective view of the cap, showing its central pivotal post, its tud,and inclined flange. Fig. 6 isa perspectivebottom view of the bolt.

This invention relates to improvements on devices which are applicableto the meetingrails of window-sashes, and designed for looking togetherthe sashes, and the object of my improvements is not only to lock themeetingrails, butat thesame time to draw them firmly together to preventleakage, and also to force them vertically,-so that they will notrattle. These objects I accomplish by the device which will be fullyunderstood from the following description, when taken in connection withthe annexed drawings.

Referring to the drawings by letter, A designates part of themeeting-rail of the upper window-sash, and A part of the meeting-rail ofthe lower sash To the rail A, at or near the middle of its length, Irigidly secure a keeper or guard, B, the horizontal bar a of which isunder-beveled, as shown clearly in Fig. 2, and located in front of anaperture, to. This keeper will be again referred to.

B designates the case of my locking-bolt, which is constructed with earsI) b, perforated to receive screw-fastenings; also with acentral hole,I), vertically through it, and also with two parallel guides, 12 bequidistant from said hole b.

(J designates the circular base of the case,

which is fitted'loosel y therein and constructed with a central pivotalpost,c, having asquared upper end. This circular base 0 is alsoconstructed. with a flanged, rising from its outer u edge and extendingabout one third around the same, its upper edge being inclined, as shownin Fig. 5. Inside of this inclined concentric flange 0, and between itand the pivotal post 0, is a short stud, 0 the object of which and theflange will be hereinafter explained.

D designates the looking-bolt, which is conshaped groove,e, atthejunction of the tapered portion df, in rear of which is anotch, f,formed in the limb d, on opposite sides of which are shoulders g g.l/Vhen the parts B, O, and D, which are each cast entire, are puttogether, the stud c on the bascO is received in the notch f, betweenthe two shouldersg g ofthe limb d of shank d of the bolt. through thecentral hole, I), of the case B, and receives on its squared end ahandle, E,which may be confined in its place by riveting the end of thepost, or in any other convenient manner. This handle E is constructedwith a flat downwardly-curved grasping portion, and with a shoulder, h,which is adapted to serve as a stop to limit the circular movements ofthis handle by contact with the sides bb of the lockcase. \Vhen thewindows are shut, the handle E is turned in one direction, which shootsthe bolt out straight for a short distance toward the keeper A. Bycontinuing the movement of the handle in the same direction the inclinedflange c on the base-plate O enters the arcshaped groove cm the bottomof the bolt and forcibly raises the lip of the latter against theunder-beveled side of the cross-bar a, and not only draws the meetingrails together, but also forces the sashes vertically in oppositedirections to prevent rattling thereof, and locks them securely. Theinclined tapered lip on the bolt acts as a powerful wedge against thekeeperbar a, and rigidly holds the two sashes in their frame. By turningthe handle E in an oppo- The post a protrudes site direction theinclined flange c at first allows the front end of the bolt to drop byits own weight free from the keeper-bar a, after which the stud on thebase-plate retracts the nose of the bolt within, its case and allows thewindow-sash to be moved.

Having described my invention, I claim- 1. The combination, in ameeting-rail lock, of a keeper-bar on one of the meeting-rails, alock-case on the opposite rail provided with bolt-guides, a bolt havinga bifurcated shank, an upturned tapered locking lip,an arcshaped groove,and two shoulders formed on one of the limbs of the bolt-shank, and acircularlylnovable base-plate having a central post extending throughthelock-case,an inclined concentric flange adapted to lift the front endof the bolt, and a stud for protruding and retracting the latter,substantially as described.

2. The combination, with the 1ock-case and circularly-movablebase-plate, constructed as described, of a bolt constructed with anupturned tapered lip, shoulders, and an arcshaped groove, whereby thebolt while being shot will be raised and caused to engage with akeeper-bar, substantially as described.

3. The combination, with the lock-case provided with guides for a bolt,of a bolt having an upturned lip and two shoulders on one of its limbs,a circularly-movable base having a bolt throwing and retracting stud,and also an inclined bolt-lifting flange, and a handle secured on thepost of this base, having a stop adapted to abut against the sides ofthe lockcase, substantially as described.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.
